(o1. sri- 400) Claims.

This invention relates to agricultural and other types of machines, implements and the like embodying one or more spring-tine carrying members arranged in any desired manner of which but one example is the reel assembly of a side delivery rake.

In general, it is desirable to mount spring-tine elements on a reel bar or other supporting member in the manner disclosed and claimed in Merle W, Blooms copending application Serial No. 554,422, led September 16, 1944, for Spring Tine Mounting, now United States Patent No. 2,432,653, as such a mounting permits the tine elements to be severally readily secured to or removed from the supporting member with a minimum of time and enort. In addition, the above mentioned mounting provides a simplified, durable and inexpensive construction affording an effective supportfor the coil portion or portions of the tine element during both raking and tedding operations.

The tine elements of hay rakes and the like are subjected to extremely rough usage and breakage of such elements is a common occurrence.

And since a break in such an element usually f occurs between the coil portion thereof and the loop or part secured to thelreel bar, the types of severally detachable mountings heretofore employed are incapable, in the absence of some additional means such as a Wire loop which passes through the coil and issecured to the reel bar or mounting, of preventing the freed portion of a broken tine element from falling from the bar.

The presence of broken tine elements in hay or other material to be fed to animals and/or requiring further treatment or handling creates an obvious hazard. And although use of the additional means mentioned above will eliminate the hazard, the use of such means is not entirely satisfactory in that it is frequently intentionally or inadvertently dispensed with primarily because of the additional time and effort required in order to remove and replacel the coil retaining loop and also because such loops are sometimes lost or broken.

.And the presentinvention is directed toward and has as its object the provision of an improved spring-tine mounting affording all of the advantages hereinbefore mentioned in reference to the copending Bloom application and affording the further advantage of preventing a broken tinel element from falling from the carrying bar Without the use of auxiliary or additional parts.

The construction and application of a springtine mounting embodying the invention will become readily apparent as the disclosure progresses and particularly points out characterizing`v Fig. 1 is a partial front elevation of a rake` reel bar embodying the invention;

Fig. 2 is a View taken on line II-II of Fig. `1;

Fig. 3 is a top plan view of the structure shown in Fig. 1;

Fig, 4 is a plan view of the tine loop engaging washer element; and n Fig. 5 is a side elevation of the washer element shown in Fig. 4.

Referring to the drawing, it is seen that the invention may be applied to a tubular reel bar member orthe like I and to dual toothed springtine elements including a pair of spaced opposed coil portions 2, a tooth portion 3 extending from the outer side of each coil portion, and a loop portion 4 uniting the coil portions 2 and extending away therefrom preferably in an opposite direction with respect Ato tooth portions 3; ther outer extremity or mid-section of loop portion 4 being preferably bent or otherwise shaped to engage the top side of tubular member I with coil portions 2 disposed in spaced adjacent parallel relation with respect to the opposite or underside of member I as is best indicated in Figs. 1 and 2.

Member. I is provided with a series of longitudinally spaced pairs of alined holes or bolt receiving bores 6 and the spring-tine elements are readily detachably secured to member I by means of a part 'I having oppositely extending coil supporting portions 8 and an offset, apertured intermediate portion 9 adapted to engage the underside of member I with the aperture therein alined with a pair of bolt receiving bores 6 and by means of a carriage bolt part or element II having a head portion l2 engaged by loop portion 4 as is best indicated in Fig. 3 with its opposite or nut engaging end projecting through the aperture in the oiiset portion 9 of part 1.

The portions 8 of part 1 extend entirely through coil portion 2 and-terminate in offset ends I0 coasting with the adjacent side of bar member I so as to prevent the coil and tooth portions of a broken tine element from falling from part 1. The oiset end l of each portion 8 may be dimensioned either to rmly abut the adjacent side of member l and thereby brace the end extremities of part 'I or to be spaced from such side of member l a distance preferably `somewhat less than the diameter of the Wire of coils 2. In either case, the ends I0 and intermediate portion 91are sirnilarlyoiset` for azdis tance somewhat greater than the diameter of the Wire of coils 2 and in all cases intermediate portion 9 is offset for a distance sufficient to abut'v member l with the portion or portionsf8:,--andfthe;
